An Android App - a Deconstruction

Submitted Nov 11, 2011

We’ve built apps that are in use by over a million users to solve a real world problem, AAA Roadside assistance. We’ll deconstruct the app for you, peeling back the layers including design, mixing native and HTML5, maps, GPS, Camera, dealing with fragmentation aided by tracking crash logs, and reporting/analytics.


We’re going to walk through the various components and layers that went into making this app.

First off given that the apps primary purpose in emergency response / assistance, it was important to ensure a clear UI design to get the user the help they needed as quickly as possible.
To maximize shared effort in building an iPhone and Android equivalent of the app, the interface of the app was built using a mix of Native and Web components. A tricky approach given the need to match style and navigation patterns across native & web as well as across iPhone & Android.

Beyond the interface the app’s primary use case involved GPS location services and using a custom maps layer (ie no google maps). And another use case involved the use of cameras.

Put all these components together with a large install base (over half a million users), meant dealing with the Android fragmentation problem head on.

So all in all this is story of what went into building this app and the lessons learnt.
